You're well under the 180 days until the end of September so you should be able to make ADRs online. As has been stated in other threads though the app has been a bit flakey lately. I'd suggest you grab a coffee and call WDW to make your ADRs the old fashioned way.
Calling for any ADR is the way to go.. but you can't reserve dinner shows online anyway. I read about countless problems online ressies, I don't need the headache. I'd rather talk to a real person to do all of my adrs and I haven't had a problem as of yet!
